Document Management Software for Scanned Documents

[samhain]

We have a nifty scanner at work which is under utilised. The secret to good records management is not necessarily down to hardware but the software that can be used which will allow easy and accurate retrieval from thousands of documents based on some kind of search criteria, NI Number, name etc.

Does anyone have any experience of this type of product and can give advice as to what to look for.

This is for work.

Thanks
